Particles, Plasma and Electromagnetic Waves in the Inner Heliosphere

太阳系近太阳环境中的等离子体物理是太阳物理学中的一个重大挑战。日冕和内日球层是产生太阳扰动的关键区域，太阳扰动影响日球层并形成空间天气，新的短波射电观测（特别是低频阵（LOFAR））将弥补差距，为研究内日球层太阳现象和空间天气的起源提供新的机会。高能电子的加速、传播和无线电发射将结合模拟和新的观测进行研究。具体而言，LOFAR无线电数据的分析与美国航天局靠近太阳的帕克太阳探测器的现场分析相结合（前所未有）将提高我们对日光层内部过程的理解。

The physics of the solar system plasma in the near-Sun environment presents a major challenge in solar physics. Solar corona and the inner heliosphere is the key region of space responsible for the birth of the solar disturbances that affects the heliosphere and forms the space weather.The new radio observations at decameter wavelength (notably with Low Frequency Array (LOFAR)) will bridge the gap and will open new opportunities to study the solar phenomena in the inner heliosphere as well as the progenitors of space weather. Acceleration, propagation and radio emission of energetic electrons will be studied combining the simulations and the new observations. Specifically, the analysis of LOFAR radio data in combination with in-situ NASA Parker Solar Probe close to the Sun (as never before) will improve our understanding of the processes in the inner heliosphere.
